Hydration Status and 60 m Sprint Performance in Students of Yogyakarta Province, Indonesia

Abstract

Background and Objective: Studies reported that adolescents in Indonesia had low fluid intake and were dehydrated. Dehydration may alter cognitive performance performed by adolescents in school. It may also impair physical fitness. The aim of this study was to examine the difference in hydration status and 60 m sprint performance between boys and girls and to seek the correlation between hydration status and 60 m sprint performance. Material(s) and Method(s): In this cross-sectional study, height, weight, body mass index (BMI), urine specific gravity (USG) and 60 m sprint performance of 98 boys and 140 girls aged 15-18 years old of a public senior high school in Yogyakarta Province were measured. Statistical analyses with t-test, Kolmogorov-Smirnov Z test and Spearman's rank correlation were performed. Result(s): The differences in hydration status and 60 m sprint performance between boys and girls were significant (p<0.01). Boys had lower USG and achieved higher scores than girls. Hydration status and 60 m sprint performance had a significant negative correlation in boys and together with girls (p<0.01) and had an insignificant positive correlation in girls alone (p>0.05). There were significant differences in hydration status and 60 m sprint performance between boys and girls. Conclusion(s): These findings indicated that boys have achieved higher performance scores than girls. Furthermore, students with lower hydration status achieved a better 60 m sprint performance than did students with higher hydration status.Copyright © 2019 Audy Swari Prahasti et al.
